The line of severe storms that moved through Maryland extended from Tennessee to New England Saturday afternoon, prompting tornado and severe thunderstorm warnings.

The National Weather Service issued a bulletin shortly before 5 p.m. indicating a funnel cloud reported by law enforcement at about 4:40 p.m. in the area of Cape St. Claire, Anne Arundel County.

A police officer who was at Sandy Point State Park at the height of the storm told 11 News his police vehicle sustained damage and a window was blown out. It was not known whether wind or debris caused the damage.

The storms brought a potential of producing hail up to the size of quarters and damaging winds between 50 and 60 mph and a risk of tornadoes.

The most severe storm cells traveled through the Baltimore region shortly after 4 p.m., when a tornado warning took effect for northern Prince George's and central Anne Arundel counties for much of the hour.

Heavy winds shortly after 4:30 p.m. prompted the closure of the Chesapeake Bay Bridge in both directions, where 60 to 70 mph winds were recorded. The bridge was reopened shortly after the storm passed.

When issuing the afternoon tornado warning, 11 Insta-Weather meteorologist John Collins said the weather service found conditions palpable for rotation in the clouds associated with the fast-moving storm.

Radar detected a valid indicator of circulation in clouds 1,000 feet up in the storm southeast of Arnold, Collins said.

Earlier in Saturday, Baltimore Gas and Electric Co. announced it was closely monitoring the weather and has put crews in place as a precaution. Customers with power outages should call BGE at 877-778-2222.

Shortly after 4:30 p.m., BGE reported more than 12,000 power outages, more than 9,800 of which were in Prince George's County and more than 1,300 outages in Anne Arundel County.

Later in the evening, BGE announced restoration of power to almost 9,300 customers by 9 p.m. The utility reported more than 14,900 customers lost electricity at the height of the outages.

Earlier Saturday afternoon, tornado warnings issued in western Maryland, and the severity of the storms also extended to western Massachusetts, where tornado warnings were also issued.
